I've run wires to behind the head unit was unsure of which wires they are for the head unit And I already had a pair of Rockford fosgate speaker in my old ute that i took out to put in the hilux
Wanting to install a pair of 6x9 speakers in the back of the cab but I have no idea which wires are which if anyone can help would be great and also is it worth putting an amp in as well
